"On graphics properties there is no HDR feature". Then the RX 480 HDMI out is not supporting it, why, no idea. What HDR content are you trying to view?

This monitor does not support HDR on Display Port.

Win 10 does not support HDR so when HDR is on from monitor menu the colors are washout what the reviews say and what I witness in another monitor but in my monitor HDR on HDR off either way nothing changes 

Problem solved there was a setting under display settings in win10 to turn on and off HDR.  

     Thanks!

Please post a picture of the Display Settings HDR setting. Concerning the reviewers washed out HDR, read this.

Thanks! And you did not see an HDR toggle (On/Off) in the AMD control panel?

There is nothing in the AMD control panel regarding HDR.

DP 1.4 supports HDR, the monitor does not support HDR through DisplayPort.

Yes with DP the HDR option is not active.

You can read it on monitor's manual too.

Thanks!

Can you help me, I have the same issue. I have the U2718Q monitor, but can't get HDR to work. In the Settings > Display menu, there's no option to turn HDR on.

I'm running Windows 10 Pro, with a GTX 1070 graphics card (latest versions of both). The monitor is connected via Display Port.

This monitor does not support HDR through Display Port. You have to use HDMI

In the U2718Q User's Guide =

* To view HDR content (movie or game)
- Open the Windows 10 Display Settings. HDR and advanced colors should be set to On
